It's hard to feel good about yourself when you don't look good. Instead of wearing clothes that are too big or too small, find articles that fit well enough to be flattering. If you're unsure of what size you should be wearing, consult with a sales associate for assistance. She can likely make a recommendation or take your measurements. If you're ordering online, then keep in mind that sizes vary by company. Don't assume that if a large fits you on one site, then it'll fit on another. It's important to know your measurements and consult each site's sizing guides before purchasing. Ill-fitting clothes are often a result of "vanity sizing." Designers may mark a true size 8 garment as a size 4 in order to make customers feel good about themselves. Size ranges can complicate shopping, too: missy (or misses), junior, women's and petites.
If you have an "average" figure - nothing is out of proportion; you don't have a high or low waist; and your height is in an average range - then you're a missy or misses size. Women's sizes tend to fit women with a lower, larger bustline with extra weight through the arms and back best. So if you're a size 16 and fit the description of a women's size, then try that instead of a misses' 16. If your bottom is narrow and you're slim, or you simply like for your clothes to fit closely, then try a junior size. Petite clothing is meant for women who are 4'11"-5'3" or those with smaller ribcages, or shorter arms and legs.
